Carbon build-up around the ends of your spark plugs can make them difficult to remove. Luckily, it can be done—and all you need is some WD-40 and a pair of pliers.
To remove stuck spark plug wires, follow these steps:
  • Start by lubricating the edge of the spark plug wire with some WD-40. Specifically, you’ll want to spay along the edges where the plug wire and the valve cover or distributor cap meet (depending on which end of the wire is stuck).
  • Use a pair of pliers to hold and twist the plug end back and forth. Most auto shops carry pliers especially made for spark-plug removal.
  • Firmly pull up on the pliers as you twist the plug back and forth until it pops free.
In some cases, your spark plug wires can get really stuck—if you’re having trouble loosening them yourself, it may be necessary to take your Toyota Camry into a service shop for some technical assistance.
